AWS A5.5 E9016-B3
Tsanangudzo: R406 is pearlitic heat-resistant steel electrode ine yakaderera-hydrogen potassium coating ine 2.5% Cr - 1% Mo.Both AC uye DC inogona kushandiswa, uye inogona kusungirirwa munzvimbo dzose.Iyo weldment inofanira kunge isati yapisa kusvika 160 ~ 200 ° C isati yave nemoto.
Chikumbiro: Inoshandiswa kushivirira Cr2.5Mo pearlitic inodzivirira kupisa simbi zvimiro, senge tembiricha yepamusoro uye yakakwirira-kudzvanywa mapaipi ane tembiricha yekushanda iri pasi pe550 ° C, michina yemakemikari yekugadzira, uye petroleum inopwanya michina.
Kemikari yakagadzirwa nesimbi weld (%):
C | Mn | Si | Cr | Mo | S | P |
0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Mechanical zvimiro zve weld simbi:
Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) Normal Temp. |
Guaranteed | ≥590 | ≥490 | ≥15 | ≥47 |
Diffusion hydrogen zvemukati mesimbi yakaiswa: ≤4.0mL/100g (glycerin nzira)
X-ray kuongorora: Ini giredhi
Yazvino inokurudzirwa:
Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
WeldingCurrent (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 350 ℃ isati yaitwa welding;
2. Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, uye tsvina pazvikamu zvewelding tisati tasveta.
